Abstract (en)

[origin: US2012297485A1] To improve the responsiveness of a system call process without compromising safety, an information processing device according to the present invention includes: an application identification unit configured to identify a program being executed in the information processing device, by acquiring the application identifier; a caller identification unit configured to identify a caller indicating a portion of the program from which a program code is called when the identified program calls the program code; a checked-application management unit configured to manage a check result which is information including a result of previous check for safety of executing the identified program; and an attack check determination unit configured to determine, based on the identified caller and the check result, whether a check if the identified program is under attack is to be made.
